COIN-OPERATED DOOR-LOCK.

toilets, and lavatories upon the depositing of a predetermined denomination of coin or check. And to these ends the invention consists of a coin or check-controlled lock mechanism adapted to be positioned on the door o,f.a compartment and having means interlocking with the sash of the door, adapted tohe released upon the insertion of a coin or check in the said lock mechamsm.

Other objects will appear and be better understood from that embodiment of my Invention of which the following is a specification, reference being had to the accompanying drawings forming part hereof, in which:

Figure 1 is a front elevational view of a door showing the exposed portion of my invention applied thereto. Fig. 2 is a rear elevational view of the lock having the back portion of the casing removed so as to show the inelosed mechanism. Fig. 3 is a horizontal cross sectional yiew taken on the line 3-3 in Fig. 2. Fig. 4 is an enlarged detailed front elevational view of the indicator. Fig. 5 is a horizontal cross sectional view taken on the line 5-5 in Fig. 4. Fig. 6 is a vertical cross-sectional View taken on the line G t; in Fig. 2. Fig. 7 is a perspective view of a portion of the door sash showing a portion of the lock mechanism thereon.

The lock a may be positioned at any convenient location on the door 6, but it is preferred to be within easy reach of an operator, as shown in Fig. 1.

When the door is locked as shown in Fig. 2, the bolt 5 is engaged with the keeper 6 mounted in the sash of the door 0, This bolt operates in a casing which is positioned a spring 8, for pressing the bolt outwardly This spring surrounds Specification of Letters Patent.

a rod 9, that projects beyond the casing and is loosely connected to a rock-arm 10 adapted to be swung on the pivot 11, and provided at its lower end with a toe 12. A second rock-arm 13 is pivoted at 14, and is provided with a toe 15 at the lower end. A lug 16 prevents the backward movement of the toe portion. which backward movement is caused by the leaf-spring 17 pressing forwardly the upper portion of the rock arm 13.

Mounted at the upper portion of the rock arm 13 is a knob or handle 18, that projects out on the face of the door, and which travels in a uide slot 19. A chute 20, opening in the fiice plate 21 on the door. communicates with the interior of the casing 22 which surrounds the mechanism, and as the coin d is dropped into the chute from the front of the door, it will fall into engagement with the toes 12 and 14, and be held thereinbetweenfas shown in Figs. 2 and 6.

A tongue 23 is slidingly fitted in the cas in 24 and is provided with an extending rod 25, which operates in a collar 26. This collar acts as a stop for the spring 27 which surrounds the rod, and which is compressed when the tongue 23 is retracted, as shown in Fig. 2.

Connecting the toe portion of the arm 10 with the rod is a link 28, shown in the drawing in the form of a spring. Upon the door 6 being closed the tongue contacts with the plate 29, mounted on the sash of the door, and the tongue is forced to the retract ed position. Obviously, upon the door being opened the tongue freed from the plate 29, is forced outwardly by the spring 27; this action is sufficiently strong to draw back the toe 12 of the arm 10 and widen the space between the toes 12 and 14, Whereupon the captured coin (Z will drop into the money cup 30; this cup is provided with a hinge or hasp portion 31, which is adapted to be secured to the casing 22 by the cooperation of the staple 32 and the lock 33. The portion 34 of the casing 22 is adapted to be slidingly fitted to the said casing as it is desirable to have access to the coinengaging mechanism when such is necessary; and the lower part of such portion 34 is constructed so as to be detaehably secured to the money-cup 30.

Positioned in the lock is a rod 35, which operates in a guide 36, and is pivotally connected to a lever 37 A spring 38 surrounds the rod and is so connected to the rod and guide that upon the rod 35 being retracted, the spring is tensioned or stretched and operates to project the rod outwardly, when permitted. Similar to the operation of the above described tongue 23, the rod 35 is normally disposed outwardly and is forced into the retracted position shown in Fig. 2, by the plate 39 carried by the door sash 0. This rod operates the indicating mechanism 6 and when retracted, causes the said mechanism to assume the position shown in Fig.

2. The lever 37 is pivoted at'40 and is connected at the lower end to a rack 41, which engages with and operates atoothed wheel 42. This rack is kept into engagement with the wheel by the operation of a leaf-spring 43 which is carried by the plate 44. The wheel carries a dial 45, which is protected by a casing 46 mounted on the face of the door. This casing is provided with a recess 47 which permits the exposition of a predetermined legend, as the wheel is operated by consecutive openings of the door; in order that the wheel may be rotated in one direction only, a pawl 48 is carried by the wheel and is positioned to engage with a ratchet 49 mounted on the shaft of the wheel. In the drawings the mechanism is shown in the locked position, as when the compartment is unoccupied. The rod 35 upon being retracted, causes the dial 45 to expose Vacant and the tongue 23 being retracted allows the toe portion to go forwardly; the spring 8 manifestly projects the bolt 5 into engagement with the keeper 6 in the sash.

To operate, the prospective occupant of the compartment inserts a predetermined required coin, and as the coin falls into engagement with the toes of the rock arms 10 and 13, the operator moves laterally the handle or knob 18. This swings the rock arm 13 and pushes the toe l5 forwardly; which action, through means of the inter-position of the coin, pushes the toe 12 backwardly, thus swinging the rockarm. As the upperock-bolt 5 is retracted and the door is in position to be opened. Upon the door being opened, the spring 27, as above described, projects the tongue 23, allowing thereby the release of the coin, which falls into the money-depository. Simultaneously with the opening of the door the spring 38 is permitted to project the rod 35 outwardly, which, through the lever 37, pushes forwardly the rack 41, but by virtue of the pawl engaging with the ratchet the wheel is rotated and turns the dial so that Occupied is exposed. As the door is closed, the tongue 23 is cammed inwardly by the plate 29, and similarly the rod 35 is retracted. But it will be seen that as the rod moves inwardly and retracts the rack bar, the wheel is rotated independently of the dial, as the pawl carried by the wheel, slides over and does not engage with the teeth of the ratchet. Obviously, the dial is operated onlynpon the o ening of the door, and upon the, occupant o the compartment vacating, the door is opened and the dial exposes the third quarter thereof marked Vacant.

What is claimed as new is:

A look comprising a casing having a coin slot, a rock arm )ivoted in the casing adjacent the'slot, a olt operatively connected with one end of the rock arm, a spring pressed tongue operatively connected with the other end of the rock arm and having an end portion projecting beyond the edge of the casing, and means movably mounted for holding a coin against the rock arm whereby the said means and the said rock arm may be moved simultaneously to retract the bolt.

In testimony whereof I ailix my signature in presence of two witnesses.
